We cannot add a border to an Android button using Button view attributes, to do so we need to create an XML file in the drawable folder and set this drawable XML as background to the Button view.
Examples :
1. button_border.xml: Place this file in drawable folder.
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<stroke
android:width="4dp"
android:color="#000000" />
</shape>
2. activity_main.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.code2care.example.whatsappintegrationexample.MainActivity"
tools:ignore="HardcodedText" >
<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:background="@drawable/button_border"
android:text="Click" />
</RelativeLayout>
Result
